Flushing and Progresively harvesting

So...I was just thinking about my SCROG and how much more it stretched than I had originally planned. Now that harvest is getting near I think I may want to chop about half (top 5" of 10-12" total above screen.) and let the bottoms get more light. But, what about flushing? I do believe in flushing and I guess the only way to accomplish this wouyld be to run the bottoms as an extra long flush with maybe just some sweetener? Or flush, chop, restart nutes, flush again a week later? I don't know, just curious what some of your thoughts on that would be. Thanks.

You can always flush with molasses, I wouldn't bother giving it more nutes though just continue the flush. the lower buds should mature within a few weeks or less..

Edit, my bad I just noticed this was in the hydro section. Not sure if its the same but something to look into.. I would still stay off the nutes and just do the extended flush but I have 0 experience with hydro.
